Tonsil, surface epithelium - Intense Cystatin A immunostaining occurs across all epithelial cell layers. A weaker staining is also seen in subepithelial inflammatory cells and endothelia of subepithelial vessels. Endothelial cell staining is only seen in vessels adjacent to strongly positive epithelial tissues. |

Tonsil, surface epithelium - Intense Cystatin A immunostaining occurs across all epithelial cell layers. A weaker staining is also seen in subepithelial inflammatory cells. This may represent tissue contamination in case of very high levels of target protein or cystatin A secretion. |
